Anti-Scan Feature
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
To provide added security, the RKE keypad is disabled for 1 minute after 35 button presses without a valid entry code being entered. The RKE keypad flashes during this 1-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-Scan is turned off after 1 minute of RKE keypad inactivity.
